In this architecture, new protocol stack and packet encapsulation were proposed to help implementation of DTV services over Ethernet link. A simple quality of service (QoS) structure was provided in traffic control of nodes to achieve QoS requirements of DTV delivery. Experiments were proceeded successfully to implement the idea. Finally, a short evaluation to QoS provisions was given, achieving good results.展开更多

The necessity of congregating hot TV resources is discussed via analyzing the scale-free properties in DMTN. The self-organized parallel broadcasting technology （SPBT） and the uniform content locator （UCL） are studied to utilize availably transmission channels and to help consumers to communicate with each other expediently. Experimental results show that DMTN can provide not only traditional TV services on schedule, but also digital interactive TV services on demand by using a single channel.展开更多
